as you may know, all the netcasts rely on Feedburner feeds. Unfortunately, the situation is very unclear, if Feedburner will be around for long.
Some features has been already disabled, but Google gave signs that the Feeds will stay intact.
If the the feeds will be shut off, the netcasts will get different feed. That would be a disaster, because it is like a start from scratch. Therefore we'll keep on using the Feedburner feed addresses as long as possible.
I hope it won't change. I found some related articles. Check the, if you want to know more about that matter.
Thanks for listening to our netcasts and I'm hoping you have a lot of fun with them.
